Hi,

I've added the following clientcontextmenu to a RadListBox (with checkboxes)

    
            function showCheckListboxContextMenu(sender, eventArgs) {  
        
                var menu = $find("<%= checkListboxRadMenu.ClientID %>");  
        
                if (menu != null) {  
        
                    var item = eventArgs.get_item();  
        
                    var listbox = item.get_listbox();  
        
                    document.getElementById("contextMenuCheckListboxID").value = listbox.get_id();  
        
                    menu.show(eventArgs.get_domEvent());  
        
                }  
        
            }

On the line "var listbox = item.get_listbox();" i get an error Object doesn't support mproperty or method.
So i replaced the item.get_listbox() with item._parent and then it does work. But i believe it would be better to call the get_listbox() method.

Any ideas about why i get that error? The client-api documentation states that there is such a method and i even see it in the Visual Studio watch window when i debug the code. I'm using Telerik assembly version 2009.2.701.35

Carriage Returns when exporting grid using ExcelML

Hi,

I cannot seem to figure out why carriage returns are not being displayed in the excel documents being produced by using the .ExportToExcel() call.

My .aspx file includes the following:

                        <form id="form1" runat="server">         
                    <asp:ScriptManager ID="ScriptManager1" runat="server" />         
                    <telerik:RadGrid ID="radGrid" runat="server"></telerik:RadGrid>         
                </form>         

My code behind pulls data from my database and then does the following:

                            radGrid.DataSource = ds;         
                    radGrid.DataBind();         
                     
                    radGrid.ExportSettings.ExportOnlyData = true;         
                    radGrid.ExportSettings.IgnorePaging = true;         
                    radGrid.ExportSettings.Excel.Format = Telerik.Web.UI.GridExcelExportFormat.ExcelML;         
                    radGrid.ExportSettings.FileName = "excel_export.xls";         
                    radGrid.MasterTableView.ExportToExcel();         

When I query the database I loop through the record set to manipulate the data. For example, I use System.Web.HttpUtility.HtmlDecode("string here") to render html encoding properly and if I add .Replace("\n","[line break here]") I see the bracketed text in the resulting excel document.

But I can't get an actual line break to appear! I've tried replacing both "\r", "\n", and "\r\n" with Convert.ToChar(10).ToString(), Convert.ToChar(13).ToString(), and Convert.ToChar(10).ToString() + Convert.ToChar(13).ToString() --- nothing works.

If I use .Replace("\n","<br />") and change the export format to Telerik.Web.UI.GridExcelExportFormat.Html I see the line breaks, but new rows are created is Excel - which renders common excel functionality like sorting and filtering useless.

Help!

Export to pdf - column alignment

Hi

I have looked at several threads on this but have not yet found a solution that works.
I must be missing something.

Using this code behind to set the column width works OK so I was trying to add the
column alignment in the same sub, but the alignment always defaults to left for items and centre for headers.
What am I missing?

    
              Protected Sub ButtonGenPdf_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonGenPdf.Click
        RadGridGenerateList.MasterTableView.Font.Name = "Arial"

                    RadGridGenerateList.ExportSettings.ExportOnlyData = False

                    RadGridGenerateList.ExportSettings.OpenInNewWindow = True

                    RadGridGenerateList.ExportSettings.IgnorePaging = True

                    RadGridGenerateList.ExportSettings.Pdf.PageHeight = Unit.Parse("210mm")

                    RadGridGenerateList.ExportSettings.Pdf.PageWidth = Unit.Parse("296mm")
        RadGridGenerateList.Visible = True

                    RadGridGenerateList.Rebind()
        For Each item As GridPagerItem In RadGridGenerateList.MasterTableView.GetItems(GridItemType.Pager)

                        item.PagerContentCell.Controls.Clear()

                    Next

                    DefineColumnWidths()
        RadGridGenerateList.MasterTableView.ExportToPdf()
    End Sub

            Protected Sub DefineColumnWidths()  
        
                    For Each col As GridColumn In RadGridGenerateList.MasterTableView.RenderColumns  
        
                        Select Case col.UniqueName  
        
                            Case "Region"  
        
                                col.HeaderStyle.Width = Unit.Pixel(100)  
        
                                col.HeaderStyle.HorizontalAlign = HorizontalAlign.Left  
        
                                Exit Select  
        
                            Case "Name"  
        
                                col.HeaderStyle.Width = Unit.Pixel(200)  
        
                                col.HeaderStyle.HorizontalAlign = HorizontalAlign.Left  
        
                                Exit Select  
        
             etc etc

Thanks a lot for suggestions!

Edited rows losing values when adding new row

Hello,
I have a grid with all rows editable when it loads using InPlace edit mode. If I edit a value in a field on one of these rows, then click insert to add a new row to the grid, the values I entered in the row that was already part of the grid are lost.

Is there a way to avoid this?

The edits and the newly added row need to be saved at one time, I cannot do partial saves to my data source.
Thanks
-marcos

[Solved] div height "collapses" on RadTabStrip mouseover

I have a Q2 2009 RadControls for ASP.Net AJAX RadTabStrip on a web page with NO multipage. I use the tabstrip strictly as a navigational tool. Below the tabstrip is a div with some plain old text paragraphs that sits in a contentplaceholder from my masterpage. In IE8 compatibility view, when I hover over one of the tabs on the strip, the div containing the text "collapses" and cuts off the content from the bottom. This doesn't occur in IE8 native mode, Firefox, Chrome, Opera or other modern browsers. Any thoughts? This is driving me mad!

RadGrid on a page with multiple RadWindowManager opens wrong ConfirmTemplate

I have a page with 2 windowmanagers on it, some controls have their own managers.
This is the manager on the control with the grid.

    
            <telerik:RadWindowManager ID="mgrWindow" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="true" runat="server" > 
        
                <Windows> 
        
                    <telerik:RadWindow ID="EventDetailsBulkAdd" Behaviors="Close" Width="447" Height="395" Modal="true" NavigateUrl="EventDetailsBulkAdd.aspx" runat="server" OnClientClose="OnWindowClose" /> 
        
                </Windows> 
        
            </telerik:RadWindowManager>

I add the confirmtemplate to the window manager on the serverside.

    
            mgrWindow.ConfirmTemplate = new Designer.Web.Controls.ucConfirmEventForm(this.Page);

In the grid I have a delete button which uses the confirmtemplate.

    
            <telerik:GridButtonColumn HeaderText="Remove" ConfirmText="{FormName}" ConfirmDialogType="RadWindow" ConfirmTitle="Remove" ButtonType="ImageButton" CommandName="Delete" UniqueName="colRemove" ImageUrl="~/Images/icon_delete.gif" > 
        
                            <HeaderStyle HorizontalAlign="Center" Width="60" /> 
        
                            <ItemStyle HorizontalAlign="Center" /> 
        
                        </telerik:GridButtonColumn>

When I click on the delete button it does not call my confirmtemplate on this control. It calls the other windowmanagers confirmtemplate which is not set and is the first one rendered. I know default RadWindowManager functions call the first RadWindowManager that is rendered on the page. How do I get my delete button to call a specific RadWindowManager?

Update Panel issue when adding RadDock

I receive the following error in the CreateSaveStateTrigger method when adding a RadDock dynamically to a RadDockZone

{"A control with ID '39f41c90af750a469baaf9eacef10f1b6c83__53' could not be found for the trigger in UpdatePanel 'UpdatePanel1'."}

'39f41c90af750a469baaf9eacef10f1b6c83__53' is the id of the RadDock I am attempting to add.

Here is my code for CreateSaveStateTrigger:

private

void CreateSaveStateTrigger(RadDock dock)

{

//Ensure that the RadDock control will initiate postback

// when its position changes on the client or any of the commands is clicked.

//Using the trigger we will "ajaxify" that postback.

dock.AutoPostBack =

true;

dock.CommandsAutoPostBack =

true;

AsyncPostBackTrigger saveStateTrigger = new AsyncPostBackTrigger();

saveStateTrigger.ControlID = dock.ID;

saveStateTrigger.EventName =

"DockPositionChanged";

UpdatePanel1.Triggers.Add(saveStateTrigger);

saveStateTrigger =

new AsyncPostBackTrigger();

saveStateTrigger.ControlID = dock.ID;

saveStateTrigger.EventName =

"Command";

UpdatePanel1.Triggers.Add(saveStateTrigger);

}

Any help would be appreciated.

Thanks,

Brian

Image Manager Browser issue

Hi Telerik Team,

On a project we are working on for some reason we can't get the image manager in a RadEditor to upload images in I.E.

It works fine in Firefox, its accepting uploads and adding them into the file. In I.E. the upload button is faded out (disabled).

The code that sets up the managers is shown below.

    
            //set up the client folders  
        
                        string[] DocMan = new string[] { "~/ClientResources/" + log.ClientID + "-" + log.Name + "/Docs/" };  
        
                        string[] ImMan = new string[] { "~/ClientResources/" + log.ClientID + "-" + log.Name + "/Images/" };  
        
                        string[] FlashMan = new string[] { "~/ClientResources/" + log.ClientID + "-" + log.Name + "/Flash/" };  
        
                        string[] MediaMan = new string[] { "~/ClientResources/" + log.ClientID + "-" + log.Name + "/Media/" };  
        
                        //create directorys if they dont exist  
        
                        if (!Directory.Exists(Server.MapPath(DocMan[0])))  
        
                        {  
        
                            Directory.CreateDirectory(Server.MapPath(DocMan[0]));
